Numbering Plan for Ireland

The Number Plan for Ireland lists all numbers and codes that are available on public telecommunications networks. These include:

Geographic Numbers

Geographic numbers telephone numbers linked to a particular geographic location. A document showing the boundaries of Area codes and Minimum Numbering Areas (MNAs) is ComReg Document 03/147 or you can view the Area code maps online. Authorised undertakings with geographic number assignments and an OSI licence can obtain soft copies of the maps, from which more precise boundaries can be determined, by contacting ComReg’s Numbering team at

Non-Geographic Numbers & Short Codes

Non-Geographic numbers are numbers where a geographic area is not directly identifiable from the number. The services covered by these numbers include freephone services, shared-cost services, universal access services, premium rate services and nomadic services.

Mobile Numbers

Mobile numbers are typically used within public land mobile telephony networks (e.g. GSM).
